4. Cr has four isotopes:
Cr 50
Cr 52
Cr 53
Cr 54
A) Determine how many protons, neutrons and electrons each isotope has.
B) The atomic mass reported for Cr is 54.94. What does this tell us about the relative abundance of each isotope? What isotope should be the most abundant?
C) Write the electronic configuration of the Cr, taking into account that studies show that it has a paramagnetism equivalent to 6 unpaired electrons. Determine the quantum numbers for the last electron 4s of Cr.
D) Determine the effective nuclear charges for the following Cr electrons:
---An electron 4s
---A 3d electron
Please try to write everything in an organized maner and legible handwritting.

2. Given the following dictionary:
speed ={'jan':47, 'feb':52, 'march':47, 'April':44, 'May':52,
'June':53, 'july':54, 'Aug':44, 'Sept':54}
Get all values from the dictionary and add it to a new list
called speedList, but don’t add duplicates values to the new
list.
Your code should print out:
speedList [47, 52, 44, 53, 54]
